The port of Cotosa or Puerto del Paular is a mountain pass in the Guadarrama mountain range, which separates the Spanish provinces of Segovia and Madrid. It is located at 1830 m altitude. It separates the valleys of Valsaín, to the west, and Lozoya, to the east. It also separates the Peñalara massif, to the north, and the Cuerda Larga mountain range, to the south. It receives the name "Los Cotos" because of the small stone posts, called cotos, that existed until the 20th century to indicate the path that crossed it when the snow covered it.
